IMPROVEMENT IN coNDuc-r'oes FOR NAIL-ROLLING MACHINES'.

Specication forming part of Letters Patent No. 165,474, dated July 13,1875; applicat'on` led I May 18,1875.

To all whom Ait may concern:

Be it known that Il, RANSOM E. GABY, of Boston, in the county of Sul'olk and State ot' Massachusetts, have invented an Improvement in Conductors for Nail-Rolling Machines, of which the following is a specification:

The United States Letters Patent No.13sh948 show two pairs of successively-operatin g rolls of a machine for rolling, horse or cattle shoe nails. The rolls are shown as connected by means of a conductor having side walls daring toward the front, and the front wall, formed as a gate or door, is held closed by a catch so long as the nail-blanks pass in regular succes sion one by one 5 but when a blank becomes detained, so that a following blank cannot pass it, the pressure of the blanks one on the other is sufficient to force one of the blanks, through the action of the flaring sides of the conductor, outward against and to open the gate, the nails in the conductor being thrown out. The

` gate in its movement moves a Wire projecting from the naii-intercepter, which is thereby turned to cutoff the passage of the nails to the conductor.

The automatically-operating gate referred to in the above patent has been found objectionable because the nails thrown out by the action of the machine very often fall into the nipper mechanism of the nail-machine and disarrange it, injuring Such mechanism and causing much delay for necessary' repairs. If these ejected nails do not fall into the nipper mechanism they do fall on the oor and get mixed with nails ot' other lengths, and have to be picked up and assorted before being again fed through the rolls. WithY the locked conductor, as hereinafter described, the attendant ha-s onlyto remove its face and pick outthe nails, and they may be returned to the supplying box or hopper, thereby saving time. The automaticallyoperated gate is often forced open by simply a crooked nail, whereas the yielding plate of the locked conductor will not open the conductor, but will simply throw the intercepter into action, and the act-ion of the rolls will crowd the nail down and between the next rolls, and will properly deliver it.

This invention consists in a conductor for nail-rolling machine provided with a removable front plate and locking-bar, whereby, by the movement of the bar, the front plate may be removed; a's i, in a conductor having connected with it a removable front plate, and a movable channel-piece and finger projecting therefrom, to operate as hereinafter described; alsc, in a conducta' composed of a back plate having a channel, and provided with a movable channel-piece and linger, in combination with a face-plate and a holding-pin to hold a piece projecting from an intercepter, as hereinlafter described.

Figure l represents the rollersin dotted lines,

with the conductor in position between them, but with its face removed. Fig. 2 represents the conductor with its face in position; Fig. 3, a top view of the conductor, and Fig. 4 a view of the intercepter.

In the drawing. a b are the pairs of successively-operating rolls, between which the nails are fed in the usual manner, the upper pair presenting to, and the lower pair taking the nails from the conductor. This conductor is composed of a back plate, c, adapted to fit between the pairs ot' rolls, and provided with a channel or way, d, having a movable piece, e, to form one side of the channel. llhis movable channel-piece e is pivoted to the back plate c at f, is provided with a projecting linger, g, and is pressed toward the center of the channel d by a spring, h. Attached to the back plate c are two slotted projections, fi, adapted to receive the ends of the locking-bar j, pivoted to the front lplate k, and movable, preferably, by means of a key or wrench applied to an irregular post, t, projecting from the locking-bar. The removable front plate 7c is provided with a slot, m, through which projects the finger g of the movable channelpiece e, and on the front plate 7c is a notched holdingpin, a, which receives the'piece o, projecting from the intercepter p, which operates with reference to the rolls and the conductor, as does the intercepter described in the patent before cited.

When the channel d becomes unduly crowded the channel-piece e is pressed back against its spring h, and the finger q thereon, projecting through the slot m on the front pla-te k, removes the piece o of the intercepter from the' notch in the notched holder n, and permits the intercepter to out ott' theisupply of nails to the conductor; then the attendant, with a Wrench applied to the post l, turns it and the ends of the locking-barinto the position shown in Fig'. 2, dotted lines, and removes the front plate le, when the'nails may bel removed from the conductor and be replaced inthe usual hopper.

I claim- 1. A conductorfor nail-rolling machines, consisting ot' the back plate and the removable front plate and locking-ba r, adapted to operate substantially as described.

2. In a conductor for nail-rolling machines, the removable front plate and the movable channelpiece and linger projecting` therefrom, substantially as described.

3. The combination ot' the back plate c and the movable springoperated channel-piece Vand its finger with the front plate and the RANSOM E. CADY. Witnesses:
